The main reasons for the OPTIMA battery's long life are:

• Superior retention of active paste material. The Spiralcell construction immobilizes the plates, preventing the active paste from working loose, which can cause plate-to-plate shorting in conventional batteries.

• The lead-tin alloy in the OPTIMA battery contains higher-purity lead than conventional batteries, reducing internal battery corrosion.

• The OPTIMA battery's sealed design prevents loss of water which can lead to plate dry-out and failure.
